- Repeat for all other colors.
- Peche a tapa da unidade do depósito de tinta.
After filling, press and hold the Mantemento button (often depicted as a droplet or triangle with a lightning bolt) for 3 seconds to initiate ink charging. This process takes approximately 20 minutes. Do not turn off the printer during ink charging.

3. Mantemento
3.1 Comprobación dos niveis de tinta
Visually inspect the ink tanks on the side of the printer. The transparent tanks allow you to monitor ink levels. Refill ink when levels approach the lower line to prevent air from entering the system, which can affect print quality.

3.2 Limpeza do cabezal de impresión
If print quality declines (e.g., missing lines, incorrect colors), perform a print head cleaning. This can be done through the printer utility software on your computer:
- Open the Epson printer utility on your computer.
- Navega ata o Mantemento or Utilidade ficha.
- Seleccione Limpeza de cabezas e siga as instrucións que aparecen na pantalla.
Alternatively, you can perform a head cleaning by holding down the Mantemento button on the printer for 3 seconds until the power light starts flashing. Release the button and wait for the cleaning cycle to complete.
3.3 Comprobación da boquilla
After a head cleaning, or if you suspect print quality issues, perform a nozzle check to verify if all nozzles are firing correctly. This can also be done via the printer utility software or by holding the Mantemento button for a shorter duration (e.g., 1 second) to print a nozzle check pattern.
